Product Introduction

Dense fused corundum is a kind of advanced refractory material, the main crystal phase is greater than 96%, the porosity is less than 4%. It is a new type of high-purity refractory raw material made by using high-purity alumina and reducing agent according to a certain ratio in an electric are furnace after being melted at high temperature. The main crystal phase of dense corundum is a -Al2O3, the color is light gray.

Features

1.Good acid and alkali resistance. 2.Good wear resistance,corrosion resistance. 3.Volume stability at high temperatures. 4.High melting point.

Application

It can be used in iron and steel metallurgy, petrochemical, building materials, ceramics and other industries. It can also be used as the refractory ramming material and castable aggregate of the blast furnace iron trough. It is also an excellent material for making steel-making nozzles, skateboards and various corundum bricks.And it is the best refractory raw material in the series of corundum refractory raw materials for its durability and thermal shock resistance.
